New York Times report
Trump's aides have repeatedly warned him to use secure lines but he has refused to give up calling friends on his iPhone despite reports that Chinese, Russians and others are often listening in.
The New York Times cites 'several current and former officials' who detail his iPhone use.
"American spy agencies, the officials said, had learned that China and Russia were eavesdropping on the president's cellphone calls from human sources inside foreign governments and intercepting communications between foreign officials," the report says.
China's aim in listening in is to determine what he will do next. They have tried to stay ahead of him and keep the trade war from escalating. They're doing that by keeping tabs on who Trump speaks with and then feeding pro-China arguments to them via friends and business partners.
By listening to his phone calls, China is also developing a sense of which arguments and techniques can sway the President.
"Officials said the president has two official iPhones that have been altered by the National Security Agency to limit their capabilities - and vulnerabilities - and a third personal phone that is no different from hundreds of millions of iPhones in use around the world. Mr. Trump keeps the personal phone, White House officials said, because unlike his other two phones, he can store his contacts in it," the report says.
Concerns about his phone use have circulated almost since his inauguration.
There isn't much for markets here but it's an interesting look at how governments try to secure communication.
